This review is not about malice. I don't care about money. It's about telling the truth in general, whether it's about pH test strips or a deadly virus. The strips showed the acidity of tap water, two brands of bottled water, and filtered water from the refrigerator. Understand yourself. They were made in March 2020 and expire in 2 years, so the expiration date doesn't matter now, August 2020. The two of us carried out a test under lighting at a temperature of 5000 Kelvin (daylight). None of us could understand the results because of the way the stripes changed color. Only the cola test was easy to read as an acidic solution. Conclusion: These pH test strips were useless for determining an individual's alkalinity: acidity. .
